Log supported on both ends: First, overbuck 1/3 diam-
eter of log  to avoid splintering. Second, underbuck to
meet first cut and avoid pinching  (Figure 5-3C).
B
NOTE: The best way to hold a log while bucking is to use a
sawhorse. When  this  is  not  possible,  the log  should  be
raised and supported  by the limb stumps  or by using sup-
porting logs. Be sure the log being cut is  securely support-
ed.

LIMBING
Limbing  a tree  is  the process  of  removing the  branches
from a fallen tree. Do not remove supporting limbs (A) until
after  the  log is  bucked  (cut)  into  lengths  (Figure  5-2A).
Branches under tension  should be cut from the  bottom up
to avoid binding the chain saw.

WARNING
Never cut tree limbs while standing on  tree trunk.

- BAR/CHAIN MAINTENANCE
6-1.
WARNING
GUIDE BAR MAINTENANCE
OIL  PASSAGES  -  Oil  passages  at  bar  pad  should  be
cleaned to  ensure proper lubrication  of the bar  and chain
during operation. This can be done  using a soft wire small
enough to insert into the  oil discharge hole.
Ensure that the power cord is disconnected before perform-
ing any maintenance on your saw.
TO CLEAN GUIDE BAR RAILS:
Proper maintenance  of the  guide bar, as  explained in
this  section,  is essential  to  keep  your  saw  in  good
working order.
A
1.
Remove sprocket cover, bar and chain (see Section 3-
4).
5-2A
2.
Using a  screwdriver, putty  knife, wire  brush or  other
similar instrument, clear  residue from the rails on  the
guide bar.
GUIDE BAR MAINTENANCE :
Most guide bar problems can be prevented merely by keep-
ing the chain saw well maintained.
5-4.BUCKING
USING A SAWHORSE
For personal safety and ease of cutting, the correct position
for vertical bucking is essential (Figure  5-4A).
5-3.
BUCKING
This will keep the  oil passages open to provide  prop-
er lubrication to the bar and  chain (Figure 6-1A).
Reinstall  the bar,  chain  and bar  bolt  retaining nuts.
(See Section 3-4).
Bucking is cutting  a fallen log into  lengths. Make sure you
have a good footing and stand uphill of the log when cutting
on sloping ground. If possible, the log should be supported
so that the end to be  cut off is not resting on the ground. If
the log is  supported at both  ends and you must  cut in the
middle, make a downward cut halfway  through the log and
then  make  the  undercut. This  will  prevent  the  log  from
pinching the bar and  chain. Be careful that the chain  does
not cut into  the ground when bucking as  this causes rapid
dulling of  the chain.
Incorrect filing and non-uniform cutter and depth gauge set-
tings cause most guide bar problems, primarily  resulting in
uneven  bar  wear.  As  the  bar  wears  unevenly,  the  rails
widen, which may cause chain clatter and difficulty in mak-
ing straight cuts.
Insufficient guide bar lubrication and operating the saw with
a chain that is TOO TIGHT will contribute to rapid bar wear
(see Section 6-2).
To help minimize bar wear,  the following guide bar mainte-
nance is recommended.
BAR WEAR - Turn guide bar frequently at regular intervals
(for example, after 5 hours of use), to ensure even wear on
top and bottom of bar.
3.
VERTICAL CUTTING:
A.   Hold the saw firmly with  both hands and keep the saw
to the right of your body  while cutting.
B.   Keep the left arm as straight as possible.
C.   Keep weight on both feet.
CAUTION
While  the saw  is cutting,  be  sure the  chain  and bar  are
being properly lubricated.
When bucking on a slope, always  stand on the uphill side.
1.
Log supported along entire length: Cut from top (over-
buck), being  careful to  avoid cutting  into the  ground
(Figure 5-3A).
BAR GROOVES - Bar  grooves (or rails which support and
carry  the chain)  should  be cleaned  if the  saw  has been
heavily used or if the saw chain appears dirty. Rails should
always be cleaned every time the  saw chain is removed.
6-1A
2.
Log supported on 1 end: First, cut from bottom (under-
buck) 1/3 diameter of log to avoid splintering. Second,
cut from above  (overbuck) to meet first cut  and avoid
pinching (Figure 5-3B).
